Hi ALI

DOM will probably do what you want - unless your documents are large...code
follows

Document test.xml
<?xml version='1.0' encoding='utf-8' ?>
<root><test>Old</test></root>

//DOM code
System.Xml.XmlDocument d = new System.Xml.XmlDocument();
d.Load(@"C:\test.xml");
System.Xml.XmlElement el =
(System.Xml.XmlElement)d.GetElementsByTagName("tes t")[0];
el.InnerText = "New";
d.Save(@"C:\test.xml");

Hi,,
This is exactly what I am doing now ,,but the problwm is that before doing
this I am reading the xml document by using the following code
====================Start of Code=====================

XmlTextReader reader = new XmlTextReader("AppSetting.xml");

while (reader.Read())
{
if (reader.NodeType == XmlNodeType.Element)
{
switch (reader.Name)
{
case "ConnectionString":
{
applicationVars.ConnectionString = reader.ReadElementString().Trim();
break;
}

}
}
reader.Close();
====================End of Code=====================

then I try to update an element using your code but I get this Error:
the procescan not access " " because it is being used by anotheprocess

Thanks for your help.
